Title: Reheating method for desulphurized waste gas
Inventor: FUJIIKE HIROSHI
IPC: F23J15/08
Filed: 1981-09-04
Abstract: PURPOSE:To miniaturize a reheating system for treated gas, by a method wherein two liquid thermal mediums are applied as a heat accumulating body and the  two liquid thermal mediums each are made to exchange their heat indirectly  after heat has been exchanged directly between untreated gas and treated gas. CONSTITUTION:High temperature untreated gas 1 touches directly a No.1 low temperature thermal medium 31 in a No.1 thermal medium contactor 11, the high temperature untreated gas 1 is turned into a low temperature untreated gas 1' through a temperature decrease and the No.1 low temperature medium 31 is turned into a No.1 high temperature medium 31' through a temperature rise. The No.1 high temperature thermal medium 31' led to an indirect heat exchanger 20 is exchanged its heat with that of a No.2 low temperature thermal  medium 32 and No.1 high temperature medium 31' is turned into the No.1 low temperature medium 31 through the temperature decrease. On the other hand,  the No.2 low temperature thermal medium 32 is turned into a No.2 high tem  perature thermal medium 32' through the temperature rise. With this, it is possible to obtain a heat recovery and reheating method which is compact and free of gas leak.

Title: Multi-story parking device for freely driving in and out at upper and lower stages
Inventor: ARIYOSHI KAZUO
IPC: E04H6/04
Filed: 1993-05-03
Abstract: PURPOSE:To freely drive in and out a car at the upper and lower stages, by providing a slope on one side of a parking floor having a specified height and vertically moving it by a hoist by pivoting the slope on the under part of parking floor or the upper end of slope thereon. CONSTITUTION:When driving a car in in/out of the upper stage, the car drives in/out of the upper stage by ascending/decending along the slope 3B and drives in/out of the lower stage by removing the slope 3B or storing it under the parking floor 1B. In this case, when the slope 3B is stored, at first, the hook 4 of the slope 3B is unlocked and the wheel 10 is placed on the rail 7. The lower end of the slope 3B is supported by hands and pushed in so as to place a safety bar 11B on a front stopper 8. The wheel 10 is prevented from slipping off by using both flanges. Even if it runs off the rails, either one of safety bars 11A, 11B wider than the rail gauge is placed on the rail 7. Accordingly, when a stored car is present below the stage and hence it is difficult to repair the derailment, the slope 3B is temporarily made possible to be taken out or pushed in. And further, a hoist equipped with various safety devices may be attached to securely stop the slope 3B at a certain optional height so as to avoid mutual contact of respective cars and increase the safety.

Title: Substrate processor and cleaning method therefor
Inventor: NARITA MASAKI
IPC: C23F4/00
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To dry-clean an adhered object in a device which dry-etches a metal wiring film and to remove it. SOLUTION: When the processed object of a metal wiring film is dry-etched, a deposition film which is composed of C, Ti, Al, Cu and Si is formed in a vacuum container. Then, the gas of acetyl acetone, isopropyl alcohol or trimethylphosphine is introduced from a gas inlet line 26a into the vacuum container, and chlorine gas activated in a plasma generation device from a gas inlet line 26b. Thus, the surface of Al, Cu, Ti and Si is chlorinated by activated chlorine gas, and a chloride layer is formed. The chloride layer reacts to isopropyl alcohol, acetyl acetone, trimethylphosphine and alcoholate, acetyl acetone compound, and trimethylphosphine compound are generated. Since the vapor pressure of the reactive products is adequately high, Al, Cu, Ti and Si in the deposition film in the vacuum container are removed.

IPC: H02P1/46
Filed: 1982-08-11
Abstract: PURPOSE:To shorten a time when the AC synchronous motor is synchronized by supplying driving currents larger than a constant-current value on synchronizing for a time determined previously after starting. CONSTITUTION:When a power supply is turned ON, a reset circuit 7 outputs '0' at some time limit, and resets a counter 10. When the count value of the counter 10 is 128 or less, transistors 8, 9 are turned ON by an output '1' from an inverter 11, and constant voltage is applied to an inverter drive circuit 4. Consequently, driving currents larger than driving currents on synchronizing are fed. When the count value reaches 128, the inverter 11 outputs '0' by an output '1' from the counter 10. Accordingly, the inverter drive circuit 4 is supplied with constant currents from a constant-current power supply 1 because the transistor 8 and successively the transistor 9 are turned OFF.
